Troubleshooting a problem on a remote server, especially in production, is not an easy task. Sometimes it involves debugging the application code directly on the server.
But the production servers are usually run in a strict environment, where not all convenient developer tools are available.
In this article, you'll discover how to configure a running web server and debug your application using standard facilities provided by the Java platform.

Is advanced scheduling in Kubernetes achievable?Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations? In his session at @DevOpsSummit at 21st Cloud Expo, Oleg Chunikhin, CTO at Kublr, answered these questions and demonstrated techniques for implementing advanced scheduling. For example, using spot instances and cost-effective resources on AWS, coupled with the ability to deliver a minimum set of functionalities that cover the majority of needs – without configuration complexity.

I love it when I get feedback from a blog that I’ve written. I appreciate the different perspectives and insights that others bring to a topic of interest. And no blog that I’ve written has drawn more comments than my blog, “Isaac Asimov: The 4th Law of Robotics.”
The section of the blog that fueled the most comments stem from a scene in the movie I, Robot where Detective Spooner (played by Will Smith) is explaining to Doctor Calvin (who is responsible for giving robots human-like behaviors) why he distrusts and hates robots. He is describing an incident where his police car crashed into another car and both cars were thrown into a cold and deep river – certain death for all occupants.

In 1977, the Eagles released “Hotel California”, a song about drugs and the effects an addiction has on people. Putting "We are all just prisoners here, of our own device" in the context of our today’s digital lifestyle we find a lot of truth. There is a reason why Google provides most of its services for free or why Amazon wants us to have an Echo in every home or why Facebook has become our directory of “friends”. What looks pretty convenient is a threat. It is a threat to the end consumers but also a threat to the established economy. And even if we have the choice to check out any time – we will never leave.

Java applications need a certain amount of RAM on a computer to run. Each time an object or variable is declared, it needs more RAM. Simply designating enough memory to hold every value declared and run each method would lead to a bloated application.
To keep application memory requirements lean, it is partitioned in ways that require less memory and allows the application to run more quickly.
The Java Virtual Machine (JVM) divides memory between Java Heap Space and Java Stack Memory in a way that only uses memory that's needed.

We've all read the dystopian fiction, watched those apocalyptic movies and heard a myriad of prophetic warnings heralding our obsolescence. Surely now we're just a couple of years from flipping the switch on a Skynet of our own making and condemning mankind to the annals of history.
Actually, we're not entirely sure what the future holds, but it's probably not fire and brimstone. For detractors and naysayers of technology, could there be a more fitting image than Terminator 2's opening shot? A hulking, skeletal, humanoid machine crushing a human skull beneath its foot. Listening to ‘techno-skeptics' can sure make it feel as though that's the end which inevitably awaits us. If we continue down our current path of imbuing machines with increasing levels of autonomy, learning abilities and artificial intelligence, eventually we'll inadvertently construct our own obsolescence - if not destruction! We must be careful, unless we want to find ourselves subjugated by a machine army...

Handling an exception is one of the most common but not necessarily one of the easiest tasks. It is still one of the frequently discussed topics in experienced teams, and there are several best practices and common mistakes you should be aware of.
Here are a few things you should avoid when handling exceptions in your application.

IoT is at the core or many Digital Transformation initiatives with the goal of re-inventing a company's business model. We all agree that collecting relevant IoT data will result in massive amounts of data needing to be stored. However, with the rapid development of IoT devices and ongoing business model transformation, we are not able to predict the volume and growth of IoT data. And with the lack of IoT history, traditional methods of IT and infrastructure planning based on the past do not apply either.

Digital transformation is a revenue growth engine according to fifty futurists we surveyed. Many companies are already experiencing significant benefits and gaining competitive advantages. The futurists predicted the top five impacts of digital transformation on businesses by the year 2020 will be: Speed to market, Competitive positioning, Revenue growth, Productivity, and New distribution channels.

Today traditional IT approaches leverage well-architected compute/networking domains to control what applications can access what data, and how. DevOps includes rapid application development/deployment leveraging concepts like containerization, third-party sourced applications and databases. Such applications need access to production data for its test and iteration cycles. Data Security? That sounds like a roadblock to DevOps vs. protecting the crown jewels to those in IT.

Mobile device usage has increased exponentially during the past several years, as consumers rely on handhelds for everything from news and weather to banking and purchases. What can we expect in the next few years? The way in which we interact with our devices will fundamentally change, as businesses leverage Artificial Intelligence. We already see this taking shape as businesses leverage AI for cost savings and customer responsiveness. This trend will continue, as AI is used for more sophisticated patterns, and chatbots replace the traditional mobile apps.
In his session at 21st Cloud Expo, Michael Meiner, an Engineering Director at Oracle, will look at this evolution of mobile computing, along with the underlying enterprise technologies that enable this shift. Demos using Amazon Alexa and Oracle Mobile Suite will be shown.

Automation is enabling enterprises to design, deploy, and manage more complex, hybrid cloud environments. Yet the people who manage these environments must be trained in and understanding these environments better than ever before. A new era of analytics and cognitive computing is adding intelligence, but also more complexity, to these cloud environments. How smart is your cloud? How smart should it be? In this power panel at 20th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists looked at the evolving nature of hybrid cloud, how it affects enterprise IT staffing requirements, and what skills are needed to be successful.

Agile has finally jumped the technology shark, expanding outside the software world. Enterprises are now increasingly adopting Agile practices across their organizations in order to successfully navigate the disruptive waters that threaten to drown them. In our quest for establishing change as a core competency in our organizations, this business-centric notion of Agile is an essential component of Agile Digital Transformation.
In the years since the publication of the Agile Manifesto, the connection between building better software and business agility has been a tenuous one at best. But now that Agile is maturing and Digital Transformation is driving change across enterprises large and small, companies are realizing that their best bet for achieving business agility is to take the best of Agile and apply it across the entire organization.

I’ve always felt that bringing an economics perspective to our big data and digital transformation discussions is more important than a traditional accounting or even information technology (IT) perspective. Heck, I believe that a Chief Data Officer’s background should be more along the lines of economics than IT. Economics brings a forward-looking perspective on creating value (wealth). In fact, economics is defined as “the branch of knowledge concerned with the production, consumption, and transfer (capture) of wealth.”

"Our strategy is to focus on the hyperscale providers - AWS, Azure, and Google. Over the last year we saw that a lot of developers need to learn how to do their job in the cloud and we see this DevOps movement that we are catering to with our content," stated Alessandro Fasan, Head of Global Sales at Cloud Academy, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.

"When we talk about cloud without compromise what we're talking about is that when people think about 'I need the flexibility of the cloud' - it's the ability to create applications and run them in a cloud environment that's far more flexible,” explained Matthew Finnie, CTO of Interoute, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

There are many solutions that claim to democratize analytics, but they are really constrained. A meta-learning approach democratizes without limits.
The democratization of analytics has become a popular term, and a quick Google search will generate results that explore the necessity of empowering more people with analytics and the rise of citizen data scientists. The ability to easily make better use of your (constantly growing) pool of data is a critical driver of business success, but many of the existing solutions that claim to democratize analytics only do so within severe limits. If you have a complex business scenario and are looking to get revolutionary insights using them, it’s easy to come away disappointed.

I recently visited my dentist and found the experience, well, less than satisfactory. I was subjected to 45 minutes of lecturing while strapped into the dentist chair:
“You don’t brush enough times a day. You don’t brush long enough. You don’t brush correctly. You aren’t using the right type of toothbrush. You aren’t replacing the brush head soon enough. You aren’t flossing enough. You aren’t flossing correctly. You aren’t using the right type of floss.”
Good lord! It’s any wonder that my teeth aren’t just falling out of my head!!
No one likes being lectured. It’s not constructive and after a while, you just turn it off. That’s probably similar to the feeling of going to these Big Data conferences – constantly being told what you aren’t doing right. And maybe I’m guilty of doing that as well. If I am, then I’m sorry because from an audience perspective, it sucks.

I recently had a conversation with Jennifer Lent from TechTarget. She’s a respected thinker in our field and covers major trends. We spoke about the emergence of BizDevOps and its implications for businesses. We tackled a number of topics. She wrote about our conversation in a recent article, “BizDevOps: Here’s how to make it happen in your organization.”

In our first installment of this blog series, we went over the different types of applications migrated to the cloud and the benefits IT organizations hope to achieve by moving applications to the cloud. Unfortunately, IT can’t just press a button or even whip up a few lines of code to move applications to the cloud. Like any strategic move by IT, a cloud migration requires advanced planning.

We build IoT infrastructure products - when you have to integrate different devices, different systems and cloud you have to build an application to do that but we eliminate the need to build an application. Our products can integrate any device, any system, any cloud regardless of protocol," explained Peter Jung, Chief Product Officer at Pulzze Systems, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA

Five years ago development was seen as a dead-end career, now it’s anything but – with an explosion in mobile and IoT initiatives increasing the demand for skilled engineers. But apart from having a ready supply of great coders, what constitutes true ‘DevOps Royalty’? It’ll be the ability to craft resilient architectures, supportability, security everywhere across the software lifecycle. In his keynote at @DevOpsSummit at 20th Cloud Expo, Jeffrey Scheaffer, GM and SVP, Continuous Delivery Business Unit at CA Technologies, will share his vision about the true ‘DevOps Royalty’ and how it will take a new breed of digital cloud craftsman, architecting new platforms with a new set of tools to achieve it. He will also present a number of important insights and findings from a recent cloud and DevOps study – outlining the synergies high performance teams are exploiting to gain significant business advantage.

Imagine that you have hundreds of development, testing, and operations teams spread across the globe that rely on each other to execute software testing. You have 245 test environments and you release to pre-production several times a day and deploy to production once a week. How do you manage all the software tests, test data, and test environments? Traditionally, the answer would be to fill out spreadsheets or siloed tools, send emails, and hope that everything and everyone is ready at each stage of the software testing lifecycle (STLC).

An increasing number of companies are creating products that combine data with analytical capabilities. Running interactive queries on Big Data requires complex architectures to store and query data effectively, typically involving data streams, an choosing efficient file format/database and multiple independent systems that are tied together through custom-engineered pipelines. In his session at @BigDataExpo at @ThingsExpo, Tomer Levi, a senior software engineer at Intel’s Advanced Analytics group, will cover the challenges, architectural considerations, best practices, and frameworks available to enable interactive analytics integrated into a Big Data platform.

Jackson is a popular library for handling JSON in Java applications, quickly becoming the de-facto standard in the ecosystem. Starting with version 2, it has also introduced a mature XML implementation alongside its established JSON support.
Adding the Jackson XML module to the project only needs a single dependency - the Jackson XML module itself.

The Big Bang Theory is the pre-eminent explanation for the origins of the universe. It proposes, from an explosion of atoms, the universe rapidly expanded and in doing so created everything we know. But it did so in an erratic, haphazard and unstructured way. For every life form, an infinite amount of inhospitable desolate galaxies, planets and black holes were also created.
Big Data is often associated with the birth of what is known as the Third Generation of IT and many are now at a crossroads: Do they continue down the current path, hoping to stumble upon a planet Earth as they navigate a sprawling universe of information and data that continually expands in a totally unstructured fashion? Or do they apply longer term strategy, investing now to refine their technology and capitalize on the explosion of information available.

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.

When talking to clients about their business goals, most business executives are pretty clear as to what they want to accomplish, such as reducing customer churn or reducing inventory costs or improving quality of care or improving product line profitability. But these “one dimensional” business initiatives really don’t push the organization’s innovative thinking. For example, I can easily reduce marketing costs if I significantly reduce advertising and promotional spending. Or I can easily improve product line profitability by cutting all marketing and advertising spending and laying off anyone not directly related to manufacturing and sell products.

As today's digital disruptions bounce and smash their way through conventional technologies and conventional wisdom alike, predicting their path is a multifaceted challenge. So many areas of technology advance on Moore's Law-like exponential curves that divining the future is fraught with danger. Such is the problem with artificial intelligence (AI), and its related concepts, including cognitive computing, machine learning, and deep learning.

Consumers increasingly expect their electronic "things" to be connected to smart phones, tablets and the Internet. When that thing happens to be a medical device, the risks and benefits of connectivity must be carefully weighed. Once the decision is made that connecting the device is beneficial, medical device manufacturers must design their products to maintain patient safety and prevent compromised personal health information in the face of cybersecurity threats.
In his session at @ThingsExpo, Clark Fortney, Software Engineer at Battelle, discussed how designing safe connected medical devices begins with systematically analyzing cyber threats against desired functionality and making smart hardware/software architectural choices accordingly. Memory protection strategies, functional isolation, runtime checks, programming oversight, and vulnerability assessment testing are some of the key methods to increase the cybersecurity of a medical device, or any connected device that performs important functions.

"Cloud computing is certainly changing how people consume storage, how they use it, and what they use it for. It's also making people rethink how they architect their environment," stated Brad Winett, Senior Technologist for DDN Storage, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

"Suddenly a lot of companies started focusing on producing services in the cloud. I like to call it Cloud Native - everything is built for the cloud. The main concept there is to enable developers to work fast," explained Ben Bernstein, CEO & Co-Founder of Twistlock, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.

How can an organization with decades worth of accumulated ERP customizations and configurations, IT systems and customized software applications digitally transform fast enough to keep up with the rapidly changing behaviors of digital customers? That is a hard question most organizations are wrestling with today. Often complex custom IT environments served a purpose in a past era, but today where IT speed and agility are required, they serve as anchors restraining an organization from moving forward and digitally transforming fast enough to compete.

"DX encompasses the continuing technology revolution, and is addressing society's most important issues throughout the entire $78 trillion 21st-century global economy," said Roger Strukhoff, Conference Chair. "DX World Expo has organized these issues along 10 tracks with more than 150 of the world's top speakers coming to Istanbul to help change the world."

Your homes and cars can be automated and self-serviced. Why can't your storage? From simply asking questions to analyze and troubleshoot your infrastructure, to provisioning storage with snapshots, recovery and replication, your wildest sci-fi dream has come true.
In his session at @DevOpsSummit at 20th Cloud Expo, Dan Florea, Director of Product Management at Tintri, provided a ChatOps demo where you can talk to your storage and manage it from anywhere, through Slack and similar services with Tintri's web services architecture and APIs. Impress your DevOps team with smart and autonomous infrastructure.

Let’s rewind the clock a bit. A few years ago, object storage was the new technology that promised to replace file system in the secondary storage market. It would scale beyond the limits of file systems and deliver better costs. The trade-off would be lower ease-of-use with new protocols that required rewriting of the applications. File systems would keep its place as the tier-one storage solution, because of its superior performance. The world order was clear with object storage elbowing file system out of secondary storage and gradually squeezing it out of tier one as its performance improved. The marketing message was that the role of the file system was rapidly diminishing, because its technology could not keep up with the data explosion.

If you are thinking about moving applications off a mainframe and over to open systems and the cloud, consider these guidelines to prioritize what to move and what to eliminate. On the surface, mainframe architecture seems relatively simple: A centrally located computer processes data through an input/output subsystem and stores its computations in memory. At the other end of the mainframe are printers and terminals that communicate with the mainframe through protocols.
For all of its apparent simplicity, mainframe architecture can be extraordinarily complex. Mainframes process thousands of transactions per second and require an extensive infrastructure to house and maintain them. The hundreds, or perhaps thousands, of terminals (think of a bank’s ATM network) require a message routing scheme that can quickly prioritize and route transaction requests.
